Mercury 150 poor idle after hose replacement

[bigbluebirdy]

Hi folks,<br /><br />This post will get you up to date on my initial problem:<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=17;t=014438 <br /><br />Again, the motor is a 1986 Mercury 150 Black Max. It idled great (throttle in neutral) before I had to replace these hoses.<br />Now it stalls out a lot in neutral. Don't understand why. It runs great as soon as it gets a little throttle.<br />When you bring it down, it will seem like it's going to idle ok for a second and then sputter out. What could be causing this?<br />What should I check? The hoses are definitely on there nice and tight with no kinks, so it should be getting the same amount of<br />fuel it was getting before. (Hoses are the same size.)<br /> <br />Thanks for any help in advance.<br /><br />bbb<br />

Probably just needs some tinker'in with. Get that base timing right, then dial in the idle circuits, and make sure they are all sync'ed out OK.

Ok,<br /><br />I'm sure the answer to this is pretty long, but how would I go about doing that tinkerin?<br /><br />Thanks,<br /><br />bbb
